Twist-2 relation and sum rule for tensor-polarized parton distribution functions of spin-1 hadrons

Journal of High Energy Physics, 2021
Sum rules for structure functions and their twist-2 relations have important roles in constraining their magnitudes and x dependencies and in studying higher-twist effects. The Wandzura-Wilczek (WW) relation and the Burkhardt-Cottingham (BC) sum rule are

Lorentz and CPT violation in partons

Journal of High Energy Physics, 2020
A framework is presented for the factorization of high-energy hadronic processes in the presence of Lorentz and CPT violation. The comprehensive effective field theory describing Lorentz and CPT violation, the Standard-Model Extension, is used to ...

Photon–jet correlations in deep-inelastic scattering

European Physical Journal C: Particles and Fields, 2017
The reaction $$e + p \rightarrow \gamma + \mathrm{jet} + X$$ e + p → γ + jet + X is studied in QCD at the next-to-leading order. Previous studies on inclusive distributions showed good agreement with ZEUS data.

Novel corrections to the momentum sum rule for nuclear structure functions

Physics Letters B, 2022
We address novel features of deep inelastic lepton scattering on nuclei at small Bjorken variable xBj. In this regime the lepton-nuclear cross section involves the interference between the standard lepton-quark scattering amplitude for the deep inelastic

Collins and Sivers transverse-spin asymmetries in inclusive muoproduction of ρ0 mesons

Physics Letters B, 2023
The production of vector mesons in deep inelastic scattering is an interesting yet scarcely explored channel to study the transverse spin structure of the nucleon and the spin-dependence of fragmentation. The COMPASS collaboration has performed the first

Azimuthal correlations in photoproduction and deep inelastic ep scattering at HERA

Journal of High Energy Physics, 2021
Collective behaviour of final-state hadrons, and multiparton interactions are studied in high-multiplicity ep scattering at a centre-of-mass energy s $$ \sqrt{s} $$ = 318 GeV with the ZEUS detector at HERA.
